it doesn't, but if you read the OP you get a clearer picture as to why the thread was made.
TL;DR it's online brainrot that has taken over the users. Immediately after the first few screenshots GAG is referred to as a "gooner", and according to the OP, WelpHelper should have known better because according to KF law, gooners are the most vile and disgusting creatures on the planet, therefore that makes them lolcows by default.
This is why I hate "oomer" memes in general. Aside from the fact they're just lame, unoriginal and ever-changing, once you get labled as an "oomer" of something (whether it be what year you were born or if you like a certain thing e.g. boomer coomer doomer, gooner, etc...), the whitchhunts begin and whatever good image you had on the internet get's completely nuked.
For the record, I hate Welphelper and think he's an annoying fuck, but this reeks of high school girl teen drama.
